Terminal 4 is the largest and most diverse terminal at JFK, serving as the primary hub for Delta Air Lines and a wide array of international carriers. In 2026, major airlines operating out of T4 include Emirates, Etihad, KLM, Singapore Airlines, Virgin Atlantic, and EL AL. It also hosts several prominent Asian and Latin American carriers such as China Airlines, Copa Airlines, and LATAM. Following recent renovations, the terminal features two massive concourses: Concourse B is dominated by Delta’s domestic and international operations, while Concourse A serves many of the SkyTeam and international partner airlines. Interestingly, JetBlue also uses T4 for some of its international arrivals between 10:30 PM and 5:00 AM. Because T4 is so vast, it is the only terminal at JFK with its own internal shuttle bus to transport passengers between the distant "A" and "B" gates during peak flight banks.
Terminal 4 at John F. Kennedy International Airport (JFK) is one of its busiest international terminals, operated by JFK International Air Terminal (IAT), a consortium.
It serves as a major global hub, primarily for Delta Air Lines and a large number of international carriers.
